AMBROSE TOWER, OF NEW YORK, N. Y.

PUMP.

Specification of Letters Patent No. 16,558, dated February 3, 1857.

To all whom it may concern.'

Be it known that I, Aunosn TOWER, of the city, county, and State of NewYork, have invented a certain new and useful Improvement in Pumps; and Ido hereby de clare that the following is a full and exact description ofthe same, reference being had to the accompanying drawing, which makes apart of this specification.

The nature of invention consists in the application and use ofprojection or raised seats for valves, and the ebb waterway, when thedischarge pipe is so constructed or arranged as to lead the water outfrom or below the top surface of the valve seat, and out from the ebbwaterway as hereafter described.

The following is a description of a double acting lift and force pumpwith my projective or raised seats connected with it.

The drawing represents a longitudinal vertical section of the pumps,valves and seats taken through the center.

A, A are two pump barrels situated on opposite sides of the air chamberc.

The plungers c, c which are nearly of the same diameter'as the barrelsof the pumps are made hollow in the form of trunks and in place ofcarrying packing to fit the interior of the pump barrels they are packedtight by passing through the packing and packing boxes I, I and J, J atthe top of the pump barrels, by which means the packing may easily betightened without removing the plungers.

The connecting rods O', O are jointed at the bottoms of the plungers atO2, O2 and the upper ends are jointed to the vibrating lever N which maybe driven by hand or by power. I propose to make the plungers of brassor composition which is not liable to oxidation Afrom sea water, so thatthis pump may be used on board ships as a bilge or head pump.

Fis a supply pipe which leads into a waterway E which conducts the waterright and left into and through the lower valve seats opening into thepump barrels A, A.

H, H are two branch pipes leading out from the valve seat K and the ebbwaterway L up to the upper valve seats into the air chamber G and forcedout of the opening M to which may be attached a hose or pipe.

D, D, D, D are ball valves which are secured upon the projective orraised seats K, K, K, K (around which is the ebb water L, L, L, L) bythe wires B, B, B, B so that the valves are only allowed to raise acertain height from their seats. The valve seats are raised considerablyabove the level of the ebb-waterway L, so that all substances that maypass the valves may ebb down and be forced away from the valves, bywhich arrangement the liability to claying or choking is obviated sincethere is no space afforded for the lodgment of foreign solid matterwhich the water may contain upon theivalve or seat, and as the valveseat is raised considerably any solid matter which has passed throughthe valves will be prevented from returning back again or becomingdeposited in the opening of the valves. Thus ,it will be perceived by myimprovement that vessels carrying grain, etc., can be saved from dangerwhen in a sinking condition, as it is impossible for any substances thatmay pass through the basket or strainer to clog or choke the valves,thereby making my improvementof valuable consideration in themanufacturing of pumps.

I do not claim the raised or projective valve seat and ebb water as newwhen the water and other iiuids, substances, etc., are not dischargedfrom the ebb waterway L below the surface of the top of the valve seatas it will be perceived that foreign or heavy substances will flow overthe valve seat and soon fill the ebb waterway and then come in contactwith and choke the valve; therefore That I do claim as new and desire tosecure by Letters Patent, is-

The raised or projective seat K and ebb waterway L, when the water,etc., is discharged from the ebb waterway below the surface of the topof the raised or projective seat, thereby allowing all foreign or heavysubstances that flow over the seat to be instantly forced out,consequently the valve at all times has free play and can not becomechoked. 4
